state energies, is it the new password in the world? the sustainability. hello and welcome. i'm so i think that the body annual watching e going to clean energy is the future for sure. but what about its own future? its life with challenges and opportunities. as the was demand for energy e g 's is we are still not able to produce enough energy to he knew. and so she's yes, but why is it sold and how can we change that? lago has been a for on china in june with energy making head start in 1986. the state has used its favorable, a window background to generate substantial. then as you over the years, i'm allowed to host one of these you as largest wind farms and accounts for 25 percent of in the store to win the energy generation. sounds great, but what's really behind these positive headlines and our teams, as rosie,

as they see as abundance, sunshine instead of events that we know do has plenty of. but the state has hon. is this potential to become a leader in genuine energy in india? a key initiative is the chief minister, so that's our green scheme. we check with low income homes, with solar panels aiming to make them energy independence. however, in some will not do followed has been a contentious issue for tickets. and it's the lady i said have been facing the brand to frequent our cuts since the 19 ninety's. these outages have been driven by cool with shot to just be using adding device a deep i'm group management issue in the fall guts like festivals, unpredictable but as the one or just the should you let on that or not or not. and sometimes we have no electricity for 5 or 15 different loans. while i look at student screens and at night we don't have the bible for many hours. so in recent

years, the government has been focusing on electrifying villages with venue bill energy to ensure consistent energy access. what is this actually making local communities self sufficient? i decided to dig deeper and find out what's behind this on. the problem is, i'm sort of driving to about 520 kilometers from jenae to oden today. this router lady, i has received international leave for being a self reliant monte village. but due to neglect that annual energy systems has come down a decade later, it's computed economically on viable and not even a single house. here is energy independent. i visited some of them who for 10 years said as the president of the fungi it, that is the village council. and for the next 10 years, he assisted his wife to consider this move to become energy independent with renewable energy. what's his range? the key i'm following the village is through integration street lights and drinking

water plants which increase the village electricity bill is amounting to doubled up on sides funds. so he began looking into alternative means of energy. 2001 live in 2001. we introduced sola by what street lights almost is guardians, i'm should by 5. by the same way, almost yes, very by almost got safire covered 50 percent of our power bill for a few years. and then we won't be brought to a high capacity sources like wind turbines. then i had the government with green homes, but it was all up on this, making us more energy independent operators government through the scheme. so last time is we're fitting to the rooftops. the energy generated was been stored in by trees, which followed the household. davy was 56 years old, formerly the calls to be she moved into her speech. milton, proudly powered by so loud energy. either that as well as we had solar power for about one and a half years, but then it stopped working. but we tried getting the back to the beard and even

had to come and me come and check it. nothing looked i visited the cutting quintile liter to understand the status now. so were people able to rely on this bullet, bob, but for all the needs really, on this all of the over the years, the government has given people feet of use, refrigerators and washing machine has started. so the energy demand has risen. and i want to be able to get to the bottom. those don't have the capacity to buy with the. and so instead people rely on conventional power from the grid. you'd be having started system and we contacted the paperless since designated by the state to investigate any complaints regarding the solar panels and battery storage. people complain that we think we are started backing started system stopped working . now when we spoke to technicians in oceans, the fact that the reasons for this failure, one, the government did not have a proper maintenance plan in place to the local community was not educated about upkeep or capacity. i'm sorry, what is the photo up?

so don't, there are no follow up checks done to assess energy demand and usage. as people began using more appliances, the existing solar panels were in sufficient, the people said they couldn't afford upgrading this or the system or battery storage. let me know the consistent follow could help small businesses that i found most could use more than navigation systems. local shops could stay open longer and it would support education. the villages said they expected that badge of energy independence to improve their economic status, but not having reliable access to power has actually been raised have left me and allow me just one minute here. ideally, pers funded about what to do. it has to be no economic development in this area. for us, a department that i'm going to explain to me is a question. can be self sufficient by producing enough energy for them that will be no need to rely on the plate and only then when they use the defendants, encore, the follow up lines. know some of those. and those,

the transition is also highly politicized. power shortages and the debt to didn't electricity department, a b, p link to political agendas or major parties problem is 100 the owners of electricity as a long standing boot bank tactic. even though it takes a severe financial tool on the electricity department party and they'll do transition research says that there are a lot of people who don't need the subsidy and this needs to be evaluated. i wouldn't say it's for you like this, a good subsidize electricity. the costs are benefit of that as being given is a, this is absorbed by the discount through financial losses on it is being cut off subsidized in any of the higher piping consumers. and so, but i think it should also be more thought get to the in terms of who requested guntee died engineer with the department added to the steve needs to focus on reducing energy to months in order to make this transition truly sustainable along the months and they nearly $3.00 meg. oh, it is

a lot of fun. nearly 10 religious parts to use for the jewelry monitor to work up to 11 o'clock in the day because that avenue money, they have that april within and you know, it is then you cannot serve in redmond. i visited the office of the state electricity department, but didn't meet the senior officials. i made several calls but didn't get an answer . the states public exemption is expected to grow by 50 percent by 2030. the state plans to meet 50 percent of the store, the energy demand with valuable energy. sure. somebody not the space. what, what does the state needs to make this more sustainable? one integrates so a lot and then the energy into the grid to ensure as the ability to re evaluate electricity subsidies to make the move down to to 3 includes rooftop solar panels, micro goods and community solar projects in google areas, to reduce dependence on expensive centralized students solutions like back trees, full, actively involved local communities,

to foster sense of ownership and create job opportunities. salgado is the new bill . energy story is a global cost of the, highlighting the need for better planning and maintenance. yep. what's inspiring is the 5th commitment to obtaining the idea of energy with a fresh outlook on the department designated to look into the future does look like i'm going sort of uh, what is often seen as a seen um sustainable alternative for odd energy. but what happens when solar panels age and stop working efficient? the international, viewable energy agency estimates that by 2050, the amount of photo workspace waste in the was with cross about 78000000 done. and what, what do we do with orders to see that type of northern germany? let us for the farm is trying to address this issue more and more. so the funds are

being built and the getting bigger and bigger. but photovoltaic cells become less effective as the age to break. like here in northern germany, this solar farm is only 14 years old. the, the ssl to grow could and that broke out because they went installed properly plus one kid wouldn't. so the old panels have to be removed. 1600. often the operators could have sending them abroad the recycling, but they decided we all want to go in. and we also have the ability in gym and you're not far from here. well, it's about an hour and house drive away rather than half way around the world. and if you're going to vote funds the waste experts in the west and jim city of mintz, the police more more. so the farm operate is a using domestic recyclers by the panama, the container looked over at commodities and you can save a lot of energy if you use recycled material. so i'm kind of, it's also extremely important. it is to keep those recycled materials here in

germany. so they can be used again by industry into the food. if panels are exported to the same as another industry, as we lose them in, i'll follow on. the reclaimed materials were reciting. it says that cold becoming increasingly important. a year ago, writing set of a plant specifically to recycle photovoltaic panels. before that, it was nearly a sideline for the company, which just recovered to a medium on glass. now they aimed to extract additional commodities with more complex reciting procedures. no longer restricted to class and elementary and we can also recover the other components in the modules from silicon and silver to carpet and they've all, we recover all these elements. and of course they all present different challenges, which we are very intentionally focused on what's going uh, within runs april, got into this afternoon. yeah. styling is not doing it alone. a few 100 kilometers

eastern, hollow scientists at the phone who of institute a taking a closer look at the silicon powder for minute stuff. they've been working on how to recycle solar panels for a long time. now it isn't the 0 here still contains so fragmented by impulsively small amounts of metal contaminants in your minium cup of, for example, or element even from the frame. we want to recover them up to a certain point. this process is mechanical here too. but the research just kind of when you get so far with that, when you're ready to get to the remaining components, you have to dissolve them chemically like in this lovely blue solution, see the silver can be precipitated from this solution. it's the silverware off the time that it works, but not yet. from an industrial scale. some startups and companies are now entering the solar panel, recycling business. there's a bit of a silver rush going on and doesn't always get into that. we have about $18000000.00 metric tons of solar panels around the world. if we do the math,

so that's about $30000.00 tons of silver that can be recovered. doesn't look like that to know what units email is that the middle just given kinda the song scheme of things and getting nothing about the recycling of photovoltaics panels. it's worthwhile for a number of reasons. and it could become a central part of, of mining the extraction of commodities from junk island medium. it's already working smoothly for gloves. separation process is becoming more refined. so its quality is also set to improve. writing is optimistic, his business will grow and replace the old panels with new ones really pays off. as we can see, back up the solar farm and northern germany. the i looked at the latest technology so good. we only need a face of the area to make the same amount of electricity that would lead to a rise in scrapped panels in india to. but with a lapse of folks of all techs only took off the from 2010 and

2020 feet in the as domestic passenger traffic page. or is that called high or over 150000000 passengers? and that means a lot of fuel consumption. so what do we do? we either saw flying or figure out ways to save the slice without using fuse that's comes from money. forces use that in done for the supplement back from biofuels to hydrogen to electric. claim innovation is taking off quite a bit. so let's explore the future of seen those guys. it won't surprise you to hear that how we fly to the needs to change. what is the most promising solution. so a vision for you sion, a biofuels more broadly sustainable aviation fuels. they mostly made from non petroleum products like bio mass. so again, you can basically just swap the fossil fuels and heal for biofuels. i'll make a blend, but we need so much of it. the scaling up is very hot and the land that they use for other purposes, like drawing fluids or saving far. and then there's also hydrogen to think on this,

especially hydrogen made sustainably, a lot of prototypes are being tested. electric plans are a 3rd option and they can make a really compelling case here where we know we, we run off hydro power or wind power. so then to consider we have is sustainable renewal. so for us that's, that's the, the most sustainable we can do. right? now, so the for us, this is you and all the us going to of ation and one of the only people flying airplanes every day. when an a v, as in school in sweden with future pilots are being changed and flying electric lands. the paper streaming bell as they fly here. it doesn't mean much electricity . it takes around an hour and a half to charge which has been slide 45 minutes. but the result of 30 percent patchy is mostly used for pilot training or private key. get faster. tough to get

in. so hoss 1st is easier. i'm ready, correct. i've got the fast this is a super light plane, but it can only go to people with no have luggage to go. any big o e plans are faced with a big problem. heavy batteries blowing 747 to fly from say, london to istanbul. batteries will need to be this much heavier than a full time. this just going to work, since this wouldn't be 10 times heavier than the heaviest payload ever lifted. so governments and many of the industrial going back to the drawing board to redesign this is dawn bug and a vision expert we looked at on the ground infrastructure to support the transition by working together as a teacher at. but we looked at 2 main modes of operation for doing that

one, which was a battery charging system, so where the battery would remain fixed within the craft. you would plug it in as if you would like a normal device. you would just charge it. this would be the simplest way operationally speaking, but they also found that charging would waste precious time when current air traffic relies on a quick don't around bands would ok by limited space in the airport. and of course, the amount of power needed would take away significantly from the city's grid. the 2nd sort of mode of operation we looked at was a battery swapping system. and that would be where you would have pre charged x rays. and then when in that cross came in, you would remove the battery from the frame and then swap it with the one that had already been pre charged. this would save space and time, but it would require a lot of specialization that was required and you don't have anywhere. and it wouldn't be a big risk. meddling with an airframe is always dangerous. and there's also the major risk of files from holding so many batteries in one place to,

to show us what the 1st plans to be certified. but this is another huge chatting about aviation has compared to cause being certified for safety. so everything takes time for r, n d testing and tony for battery safety and the use long certification process. the urban, solomon bush with the idea of multi plans for shot in mid range flights. there's a spot of a while ago to got 90 percent of admissions from transport by 2050. all right, thank you. all those crazy sit on the equity. okay. the company then means that the district is now working on a full cedar plan and the already big ones. a plane called alice secretary, 9 passenger. the 2 crew members seem to be close to commercialization, promising to fly around 400 kilometers. that's good. carry head of the app. what's the program of the u. s. department of energy is national renewable energy lab. when you look at, if you think about their existing cargo routes that use small aircraft, their existing communities, that they're only connection is a, as

a 9 senior crap unless they take a ferry for or 6 hours type of a situation. and those are real existing route that have to be either subsidized or paid for by by communities. this is the main application so far, and it is significant at ambulances, at taxis and small cargo plans also need only small across the child has ordered 12 plants for low emissions post of deliveries, which can help local noise and equity to a study by the international central and keen aviation estimates the electric aircraft called govern 9 percent of the coming to markets. that's flights with more than 19 passengers and distances shorter than 500 kilometers. but this only accounts for 0.002 percent of go be the issue. by 2050, the estimated could be up to 0.2 percent, which is still smaller. what am i talking about? carbon emissions. but this is purely electric. we're talking about

you could also have versions of hybrid. so you could have a series hybrid which is where essentially fuel is used to power an electric my to which then powers the aircraft. so you're using fuel to georgia battery. essentially, the idea estimates of hybrids would be the next leap, navigation to the 20 thirty's, and this will contribute to a 40 percent reduction and emissions by 2050 long flights and most likely use biofuels with some parts obtained electrified, and some use of hydrogen. that proficient is a small step, but it gives us hope for the potential of the diversity of technologies that are going to need the a home sweet home. well, not so much for the planets around the world. we have complex or buildings that are we less energy efficient than the new ones. however, constructing the new building requires so much energy that it takes a long,

long time to offset the best. oh, well, is there any way to to order building can come very close to matching the energy efficiency of a new one. but transforming and we're building into a sustainable home that takes someone special, a new design in the making. it's for an older house to make it a bit more sustain a, but generally based architect, unable model and drawn, transforms existing on sustainable buildings into sustainable bonds. a green consultation. the reason why we advocate green john summations is because you can retain the building and you can actually more define the demolition of the buildings. again, there's a lot of pollution, right. and what do you do with this demolition based and it takes much longer for the oil not say to have it ready to demolish. and can you do this? would probably take me to us to do was is a john submission for the any. it could be as less as 6 months degree and

consummation process is different for each building and depends on what's needed. this residential home into night was transformed into a green building by an open my and her team for this house. all the lights and fence, look on what it into energy efficient models by what it's toilet technology, windows sizes, but increased to let an adequate natural light. and the introduction of cross ventilation means the occupants now don't have to use that ac. quite so often. of all this helps to save energy, the water. what we do is, uh the, again, do please, all of the plumbing fixtures, the little fuel fixtures, right? so it's a do a slash, a lot of losses or adapts that have a new fluid it. so that reduces that initial water consumption and water will waste

water that com. so let me make sure that is treated, collected treated energy used inside the site defense. a green consummation like this one gets water consumption by at least half and reduces energy use by around 30 percent. the idea would be to apply this green dress summation process more lightly. but do you know mega city like to night? that's not without its challenges. most notably, the cost costing uh with a green transmission really depends on what we do. so yeah, i would say between, you know, 15 to 30 last or so as you can get most of the, you know, this is the interesting thing done within the steps between 17 and 33000 utah is an affordable for many, but senior green building consultant critical to christian and sees these green solutions could still bring about 3 a change

a minute for this don phones and translates into a visit. that is uh tangible. people can feel that they can see the and noisy deduction in their bows. they can see the what the savings in their house. they can see that the friends that it makes to their environment it's, it's a huge thing to lease annually, but sustainable public building, designed by unemployment, could help save the weight for new standards, increasing q one and award from the indian green building concept for being the nation's most sustainable government building and it's an integrated come on center for the city of to night. and on simply as the green building. it is an extension of the ship on building, which is a public heritage facility, posting the offices of the local government for the city of to night. the come on center and a green volk leave that connected with the group on building what designed by under

bama and her team. jenn, i, city government wants to upgrade all government buildings to meet environmental standards as soon as possible. as one of the chief engineers explains, being the environment, the sustainable. and also what you're trying to plant is the 0. well, i've been footprint. that is the main idea. and we are also trying to a, to the existing building, also the disability and all the existing buildings to be converted to building standards, the, to look good stuff to be like 10. it is so many building. i mean these buildings. i believe it and i will say 99 percent on not just the beans on summation, not only to this one flag, but if you're able to, you know, influence. many such buildings is very,

very excessive. as we've seen today, the future of clean energy, who is immense promise, a new innovations can really help us stack of the challenges if we face. thank you for joining us. i will see you next week. let us know what, what do you like to see more of on the show? you can email us or reach out to me directly on my social media hundreds until then take it goodbyes. soft gosh, the of the the zeros c o 2 emissions. that's what the switzerland wants to achieve by 2050. they might fall

make up your own mind dw, made for mines. how can commercial trucking help protect the time? it sounds crazy, but switzerland is trying a new approach to the greenhouse gas process. it's collecting carbon dioxide produced by with industry and shipping. it's thousands of kilometers to iceland their, the gas is pumped into the ground where it's trapped and turns into a solid future technologies for a cleaner environment this time on dw science. so welcome to tomorrow. today a very special tank is waiting at us of.
